Aura: Koga Maryuin's Last War

Satou Ichirou once dubbed himself Maryuuin Kouga and lived as though he were a hero from a fantasy realm. His peculiar persona earned him bullying from classmates, prompting him to leave the school. At his new institution, he strives to appear ordinary, but a chance encounter with a blue-caped girl shifts everything. She introduces herself as a researcher traveling from the outer world to search for the Dragon Terminal. Initially, Ichirou rejects Satou Ryouko because her behavior recalls his own embarrassing past, but his resolve softens after seeing her bullied. To bring Ryouko back to reality, Ichirou embraces her and his history, and steps into the final battle as Maryuuin Kouga.
